// Use text X-scale so we can text labels on the X-axis

// Y2-axis is linear
$graph->SetY2Scale("lin");
// Color the two Y-axis to make them easier to associate
// to the corresponding plot (we keep the axis black though)

$graph->y2axis->SetColor("black", "orange");
// Set title and subtitle
$graph->title->Set("Combined bar and line plot");
$graph->subtitle->Set("100 data points, X-Scale: 'text'");
// Use built in font (don't need TTF support)
$graph->title->SetFont(FF_FONT1, FS_BOLD);
// Make the margin around the plot a little bit bigger then default
